Note:
When operating RNAhybrid, the pipeline first calculates the perfect minimum free energy (Perfect mfe *) of a putative miRNA when the entire putative miRNA binds to a perfectly complementary target site, then it calculates the minimum free energy of RNA duplex (mfe of the miRNA/mRNA duplex), abbreviated as Rd_mfe. An alignment for which the Rd_mfe to its correspondent Perfect mfe ratio (R_P_ratio #) is more than 66% is regarded as a positive alignment as described by Krek et al. (21). The P_value is calculated by RNAhybrid.
